Use the wired sensors already in your walls to build a smart security system without a required monthly fee.
A no-monthly-fee security system should still give you useful alerts, automations, and self-monitoring without forcing an alarm-company subscription.
For homes with existing alarm wiring, the strongest upgrade path is reusing the wired door, window, and motion sensors already installed and connecting them to a modern smart home instead of replacing every sensor with a new wireless subscription system.
Konnected is built for that wired alarm retrofit approach. It helps you use existing wired sensors for smart alerts, dashboards, automations, and self-monitoring workflows without requiring a traditional alarm-company subscription for the system to be useful.
Quick Answer: Smart Security Without A Required Monthly Fee
Yes, you can build a smart home security system without a required monthly fee. With Konnected, many homes can reuse existing wired door, window, and motion sensors for smart alerts, dashboards, automations, and self-monitoring workflows.
No monthly fee does not mean every security service is free. Optional professional monitoring, cellular backup, cloud services, or third-party services may still cost extra if selected. The key difference is that the core smart-home path can still be useful without a required alarm-company subscription.
If your home already has wired alarm sensors, start by deciding whether you want to replace the old alarm panel, keep it working in parallel, or get support/installer review before moving life-safety, powered, monitored, keypad, or unknown wiring.

What no monthly fee really means
No monthly fee does not mean every possible security service is free forever. It means the core system should still be useful without a required subscription.
For Konnected, what this means is:
- No monthly subscription for basic smart-home integration with 6+ platforms.
- Smart home control, alerts, dashboards, automations, and self-monitoring workflows work without monthly fees through compatible smart home apps.
- Optional professional monitoring, value-added cloud services, or third-party services and integrations may still cost extra if you choose them.
- You keep more control over the hardware and smart home workflow.
The important distinction is choice. A required-subscription alarm system asks you to keep paying for the main value. A no-monthly-fee setup should still deliver useful smart home integration, alerts, dashboards, and automations without forcing that choice.
The best security system is often already in your walls
Many homes already have wired alarm sensors installed in doors, windows, hallways, and rooms. Those sensors are still valuable even if the old alarm panel is outdated, disconnected, or tied to a service you no longer want.
Wired sensors are worth keeping because they are fast, reliable, and often already installed exactly where you need security coverage.
- They use hardwired connections instead of battery-powered wireless signals.
- They do not need batteries.
- They are already installed in useful locations.
- They are more discreet than stick-on wireless sensors.
- They cover many doors and windows without buying a new sensor for every opening.
- They save money by turning existing alarm wiring into smart home infrastructure.
- They become inputs for smart home automations.
If the wiring and sensors are still in good condition, modernizing the panel side of the system is usually a better upgrade than starting over with a new wireless kit.
Where Konnected fits
Konnected is built for homes that already have wired alarm sensors and want to make them useful in a smart home.
Instead of treating the old wiring as junk, Konnected connects many existing wired sensors to smart home platforms such as Home Assistant, SmartThings, Alexa, Hubitat, and Google Home. That lets your home use door, window, and motion activity for alerts, dashboards, routines, and automations without depending on a traditional alarm-company subscription for basic smart home value.
Konnected is the right fit if:
- The home already has wired door/window sensors or motion sensors.
- You want smart alerts and automations.
- You want Home Assistant, SmartThings, Alexa, or another compatible smart home platform.
- You want to avoid replacing every sensor with wireless devices.
- You want a choice between replacing the old panel or keeping it in parallel.

Which Konnected path fits your no-monthly-fee security setup?
A smart home security system without required monthly fees can mean a few different things depending on the equipment already in your home. If you have an older wired alarm system, Konnected can help you reuse those wired sensors and bring them into a modern smart home setup without requiring a traditional alarm-company subscription for basic alerts and automations.

- Alarm Panel Pro Interface Kit: choose this when the legacy panel, keypads, or monitoring still need to stay in place while Konnected adds smart-home visibility. Review the Interface Kit
- Smart Alarm Panels: start here if you need to compare kits, zone counts, and replace-vs-interface options. Compare smart alarm panels
Replace the old panel or keep it?
The key buying decision is whether the old alarm panel is being retired or kept in service.
If you want to stop using the old alarm panel and keypads, start with the Alarm Panel Pro 12-Zone Kit. This is the conversion route: Konnected becomes the main smart alarm panel for your existing wired sensors, and your smart home handles alerts, dashboards, and automations.
If you still use old keypads, existing monitoring, or other legacy panel behavior, start with the Alarm Panel Pro Interface Kit. This is the parallel route: the traditional alarm panel stays in place while Konnected adds smart-home visibility and automation from the same wired sensor activity.
If you are not sure what the old panel still controls, start with the Smart Alarm Panels collection or product decision guidance before choosing between conversion and interface setups.
For more detail, use the wired sensor reuse guide to confirm what can be reused, then use the replace-vs-keep guide to choose the right Konnected path.
Sensor and device caveats
Door and window contact sensors and many wired motion sensors are the clearest common examples of reusable wired alarm devices. Sirens, glass-break sensors, powered sensors, keypads, smoke/CO devices, and specialty devices need more installation-specific review before you assume they can be reused.
Other devices need more care:
- Keypads are not simple door/window sensors.
- Smoke and CO devices are life-safety devices and should not be casually treated as reusable alarm sensors.
- Strobes, powered sensors, and specialty devices may vary by installation.
- Existing monitoring and old-panel behavior can change the correct product route.
If you are unsure what your existing panel controls, inspect the system carefully or start with product decision guidance before choosing a kit.
How Konnected compares with common alternatives
Most consumer alarm brands are built around replacing the system: new hub, new wireless sensors, a new app, and often a subscription or service plan. Ring Alarm, SimpliSafe, Abode, Cove, ADT, and other mainstream systems can make sense when you are starting from scratch.
If your home already has wired alarm sensors, the decision is different. You are not only choosing a security brand. You are deciding whether to reuse the infrastructure already installed in your walls.
Konnected is strongest when wired-sensor reuse, smart-home flexibility, and no required monthly fee for basic smart-home integration are the priority. EnvisaLink, AlarmDecoder, DIY ESPHome, and Alarmo-style paths can also fit some technical users, but they usually require more panel-specific setup, Home Assistant knowledge, or ongoing DIY responsibility.
Home Assistant, SmartThings, Alexa, and local control
Home Assistant is a strong choice for local control and advanced automations, but it is not the only fee-free smart-home path for a Konnected alarm system. Konnected also works with popular platforms such as SmartThings, Alexa, Hubitat, and HomeSeer for self-monitoring and control without requiring a traditional alarm-company subscription.
That gives you flexibility. You can choose a more advanced Home Assistant setup, a mainstream SmartThings setup, Alexa-based routines and notifications, or another compatible smart home platform that fits your home.
Useful smart-home workflows include:
- Turn on lights when a door opens.
- Send custom notifications when motion is detected.
- Show sensor state on dashboards.
- Trigger routines based on door, window, or motion activity.
- Use compatible smart home apps for self-monitoring and control.
- Avoid unnecessary cloud dependency for basic sensor state when your chosen platform supports that workflow.
Konnected fits that workflow because it turns wired security sensors into smart home inputs instead of locking them inside one alarm-company app.
Reusable wired sensor checklist
Before buying, confirm:
- Existing alarm panel model.
- Whether the old panel is still used.
- Whether keypads or monitoring need to stay active.
- Which zones correspond to which doors, windows, and motion sensors.
- Whether sensors are normally open or normally closed.
- Whether any powered sensors need separate power.
- Whether smoke/CO or other life-safety devices are involved.
- Whether you want replacement/conversion or interface/parallel operation.
FAQ
Can I have a smart security system without a monthly fee?
Yes. A homeowner can use Konnected for core smart-home control, alerts, dashboards, automations, and self-monitoring workflows without a required monthly subscription. Optional professional monitoring, cellular backup, cloud services, or third-party services may still cost extra if selected.
Does Konnected require a subscription?
Konnected does not require a monthly subscription for the core smart-home path. The hardware can connect compatible wired sensors to smart-home platforms for alerts and automations. Optional services may have their own costs.
Does no monthly fee mean professional monitoring is free?
No. No monthly fee means the core system can be useful without a required subscription. Professional monitoring, emergency dispatch, cellular backup, cloud services, or third-party services are separate options and may cost extra if selected.
Can I reuse old wired alarm sensors for no-monthly-fee security?
Often, yes. Existing wired door contacts, window contacts, and wired motion sensors are usually strong reuse candidates when the wiring is accessible and the devices still work. Smoke/CO, fire, keypad, siren, powered, monitored, wireless, glass-break, or unknown devices need more caution.
Should I replace my old alarm panel or keep it?
If you are retiring the old alarm panel, an Alarm Panel Pro / conversion route is usually the cleaner starting point. If you need to keep old keypads, monitoring behavior, or legacy panel functions, the Alarm Panel Pro Interface Kit route may fit better, but it can involve additional setup and product-specific planning.
Is Konnected the same as Ring, SimpliSafe, ADT, or Abode?
No. Konnected is focused on wired alarm retrofit and smart-home integration. Mainstream consumer alarm brands often center on their own hubs, apps, sensors, and service models. Konnected is usually a better fit when a home already has wired alarm sensors and the buyer wants smart-home flexibility without a required monthly fee for the core path.
